Get PriceGeotextile is recommended for use over silt and clay soils. It is not essential in sandy soils. The decision to use a geotextile in permeable pavement should be based on the same criteria used when considering use of a geotextile for the traditional interlocking concrete pavement: 1) confinement of the base aggregate and 2) separation of the base aggregate from the subgrade soil.
Get Pricepavement. A review of the literature suggests that geotextiles are effective in performing the separation function in pavements. The primary design consideration for such geotextile are construction survivability and soil retention. Geotextile construction damage decreases exponentially with an increase in mass per unit area.
Get PriceGeotextiles, one among the different geosynthetic products, can be used for a number of functions or applications in pavement design.
